Title: Nanobubbles at the solid/water interface
Author(s): Zhang, Xuehua; Hu, Jun
Abstract: Bubbles at nanometer scale could not exist stably according to classic theories. A lot of recent experimental results, however, have proven that there are nanobubbles at solid/water interface. The images of atomic force microscopy (AFM) in liquids revealed nanobubbles adsorbed on solid surfaces and provided the direct evidence for their existence . The presence of nanobubbles at the solid/liquid interface may be related to some important interfacial phenomena, for example the hydrophobic attraction and the slippage of simple fluids near a wall. So it has profound meanings in surface science, hydrodynamics, biology and many application fields. At present the study of nanobubbles is on the initial stage and researchers have paid enough attention to its influence. In this article the indirect and direct evidence for the presence of nanobubbles and the basic properties of nanobubbles, including its formation mechanism, morphography and distribution, are reviewed. And the influence of nanobubbles on the long-rang hydrophobic interaction, fluid slippage and some biological problems is discussed.
